549433 ÷ 42 
The aim is to understand the frequency of 42 in 549433.

On to step 1:
42 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 42

Moving on to step 2:
54 divided by 42 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 42 from 54 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 42

Let's proceed to step 3:
42 can be fit into 129 3 times, resulting in a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 126 from 129 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 42

Step 4:
34 divided by 42 is 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 42

Going ahead to step 5:
343 divided by 42 is 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 1308.0
Subtracting 336 from 343 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 42

Let's proceed to step 6:
When dividing 73 by 42, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 13081.0
If we subtract 42 from 73, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
42 goes into 310 7 times with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 13081.7
Subtract 294 from 310 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 8:
42 can be fit into 160 3 times, resulting in a remainder of 34.
The next digit of our result is 3. 
Result so far: 13081.73
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 13081.738
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 42 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 13081.738
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 13081.73809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
220 divided by 42 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 13081.738095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
42 goes into 100 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 13081.7380952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
When dividing 160 by 42, we get 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 13081.73809523
If we take 126 away from 160, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 13081.73809523 with a remaining 3.4e-08.
